Abstract

Disclosed is a process for applying an electrical insulating coating onto a ferrous metal surface and the ferrous metal surface with the coating thereon. The insulating coating comprises phosphate and nitrate applied in a thin film of from about 200 mg to about 400 mg coating weight per square foot of ferrous metal surface coated.
